From the drawing board
This is the part we're proud of.
EB-001 is the first thing we've ever designed from scratch, and we drew every part of it ourselves. Keep scrolling and it comes apart.
An animated engineering drawing: the sphere is scanned into a wireframe, dimensioned (210 mm overall, Ø150 sphere), then exploded into its four parts — clear-plastic spherical body, food-safe wick interface plate, threaded drip tray reservoir (M100×2, 35 mm deep), and the Ø45 mm TPE suction mount rated for 1.5 kg.
Self-watering wick system
How it waters itself.
There's a 35 mm tank of water under the soil. A wick runs up into the roots and pulls water up about as fast as the plant drinks it, so you only really need to fill the tray every week or so. Here it is cut in half.
A cross-section of the sphere: 2.5 mm plastic wall, soil and roots in the bottom third, a capillary wick running from the water reservoir below, and MAX and MIN fill lines on the reservoir wall.
The tank and wick keep the soil damp between fills, so it's hard to forget.
A 45 mm cup that locks on and holds 1.5 kg without marking the glass.
Stuck to the glass, it sits in the best light in the house.
The idea
Why a window?
Because that's where your light is. Most flats have no room for a herb garden, but they've all got a window getting a few hours of sun a day. So that's where the plant goes, stuck to the glass and out of the way until you need it.
Window to plate
How it works
Stick it to the glass
Press the cup onto a clean window and twist it to lock. It holds 1.5 kg, so a full sphere of damp soil won't budge.
Keep the water topped up
There's a small tank under the soil and a wick that carries water up to the roots. Most weeks you'll fill it once.
Take it down to cook
The bottom unscrews like a jar lid. Cut what you need and put it back on the window.

Help us build the first batch.
ERBALLS is two of us, a father and son. Right now the sphere is still drawings and a few mount prototypes stuck to our own kitchen windows. The Kickstarter is what pays for the tooling and a proper first production run. Back it early and you'll get one of the first ones we make.
